Metals can be strong and hard, or they can be flexible. It's the special behaviour of ions that give metals their different properties.
- Metal atoms bond together and create giant lattice structures.
- Electrons delocalise into a sea that moves through the lattice.
- Metals are good conductors of electricity and heat.
- Metals are very strong and malleable.
Metals form some of our most useful materials.
From cars, to cooking, to conducting electricity, we all depend on their properties.
They can be extremely strong and difficult to melt, like this copper wire, but also extremely flexible.
These useful properties are due to a special type of bonding that's unique to metals.
